  description: Non-strict equality comparison of BigInt values
  esid: sec-abstract-equality-comparison
  info: |
    1. If Type(x) is the same as Type(y), then
      a. Return the result of performing Strict Equality Comparison x === y.
  
    sec-numeric-types-bigint-equal
    BigInt::equal (x, y)
  
      The abstract operation BigInt::equal with two arguments x and y of BigInt type returns true if x and y have the same mathematical integer value and false otherwise.
